The energy of a photon that would move an electron from level 2 to level 5 : B. 4.8 eV
The electron energy at the nth shell can be formulated:
Rh = constant 2.179.10⁻¹⁸ J
So the electron transfer energy (ΔE)
ΔE = E final- E initial
energy at n=2(level 2) = -5.3 eV
energy at n=5(level 5) = -0.5 eV
So the energy absorbed :
they would be more detailed? what type of cells though?
Answer:
Note that melting and vaporization are endothermic processes in that they absorb or require energy, while freezing and condensation are exothermic process as they release energy.
